Can I apply for a patent for Xuelongsu fungicide?

Of course. According to the inquiry of Huinong. Xuelongsin is a patented plant-derived substance for controlling nematodes, which is used to kill root-knot nematodes. Its mechanism of action is mainly to destroy the nervous system and reduce the migration, infection and feeding of nematodes, thus reducing the reproduction and harm of nematodes. Therefore, the microbial preparation containing "snow dragon element" can apply for patent.
